Non-insulated power supplies are often required when a power semiconductor, which has to be controlled using this supply, has its drive reference connected to the mains (line or neutral terminal).

Several different technologies and designs are available among solid-state switches today. The major families are the standard Triacs (triode for alternating current), the snubberless Triacs, and the ...

Triacs are used to control ac mains loads in home appliances, and commercial and industrial equipment. In the majority of applications, the triac will dissipate sufficient power to make thermal ...

Peter Green explains advantages of LED drivers based on the flyback power-supply topology: They're inexpensive; they provide an isolated output that complies with UL safety requirements; they make it ...
